Data from: Infection prevalence and density of a pathogenic trematode parasite decrease with stream order along a river continuum

Landon Falke & Daniel Preston
In lotic ecosystems, the River Continuum Concept (RCC) provides a framework for understanding changes in environmental factors and free-living communities, yet how parasite populations shift along river continua remains less clear. We quantified infections by a pathogenic trematode parasite (Nanophyetus salmincola) in >14,000 host snails across 130 stream reaches spanning 165 km in the Willamette River Basin in western Oregon, USA. Environmental factors – including flow volume, temperature, benthic algae, canopy cover, woody debris, and...
